Title: Progress made in the open source QICK (Quantum Instrumentation Control Kit) system

The latest QICK (Quantum Instrumentation Control Kit) leverages on the success of the open source QICK qubit controller introduced in April 2022 [ref]. 
The new QICK, based on the Xilinx RFSoC ZU49DR, supports the digital direct synthesis of control pulses with carrier frequencies of up to 10 GHz in 16 output channels per board.
The companion RF board can be used to replace the rest of the warm electronics used for qubit control.
We show how multiple QICK units can be synchronized by a sub-picosecond phase lock and ultra-fast communication links.
The latest QICK's new timed processor speeds up pulse generation, reduces latency and increases feedback capabilities.
We demonstrate these new features with one and two-qubit randomized benchmarking examples at U. Chicago (Schuster's lab), and Princeton (Houck's lab).
The Advanced Quantum Testbed (AQT) at LBNL collaborated with the QICK team on the development and testing of QICK as an AQT user project, including contributions to multiplexed readout, software integration, motherboard and daughterboard design, and cold-qubit tests.
